I SLTCING MAGHINE.

in Slicing Machines, of which the following is a specification.

This lnvention relates to slicing machines and has more particular reference to a SllC- I ing machine especially adapted for slicin meats, bologna and the like.

In itsbroader aspect the invention comprehends a cutting member, a'reciprocative carriage and means for advancing the object against a member which serves to regulate the thickness. of the slices.

A well known form of slicing machine is the type shown in the patent to Luschka numbered 1,044,895 in which the meat is clamped to a feed plate which is advanced by rather complicated mechanism involving an arrangement for varying the thickness of the slices.

The use of a feed plate as disclosed in Luschka is objectionable because its movement is limited and it requires the meat to be repositioned when the feed plate has reached the end of its movement. Furthermore this arrangement is objectionable because of the clamping mechanism required.

and because of the complicated mechanism required to change the advance of the plate to vary the thickness of the slices.

The present invention dispenses with a feed plate and the clamping mechanism and utilizes in the specific embodiment illustrated a set of corrugated rollers on which the object to be sliced rests. These rollers are intermittently rotated causing the object to be advanced along the carriage so as to abut against the movable plate or tray which serves to regulate the thickness of the slices without necessitating the use of the'relatively complicated feed arrangement of Luschka.

For the purpose. of illustrating one form of the invention, a set of drawings are annexed and form part of this specification. In said drawings Fig. 1 is a top plan view of the invention partly in section.

Fig. 2. is a rear elevation.

in section of the elements for adjusting the tray which regulates the thickness of theslices.

Fig. 7. is a side elevation of the clutch elements for holding the rack stationary.

l[n the drawings: A rotary knife A is actuated by suitable mechanism such as a motor A and gearing A". Obviouslyhowever the knife might be rotated by hand or by a suitable connection with a reciprocating carriage or frame B which carries the object to be sliced. This carriage is mounted as to be reciprocal past the knife. edge either on a pair of cylindrical guide rods as B, on a single squared rod, 1n a suitable groove, or a similar arrangement.

While the carriage is shown as a chute of V shaped cross section it will be'seen as the description proceeds that a square chute mightbe used or the chute might be entirely dispensed with, the object being carried directly by rollers for advancing the object to be described. In the specific embodiment of the invention, the carriage B is apertured to permit rollers C keyed to shafts C to di- 1 rectly engage the object to be sliced. While.

in the specific embodiment of the invention apair of rollers are shown as mounted on each shaft manifestly a long corrugated roller might be employed. Furthermore chains to carry the object might pass from the rear to the front set of rollers,'which would preferably take the form of sprocket wheels in this modification, to ensure the positive advance of the object carrying chains. The rollers C can be conveniently driven by meshed bevel gearsD keyed to the lower ends'of the, shafts G. One of these gears is driven by the gear E which in turn is in mesh with the bevel gear F, con-' nected to a ratchet wheel F by a suitable sleeve F, on which a gear G is loosely mounted. The drive gear carries a spring pressed pawl Gr adapted to engage the ratchet wheel F and drive it and bevel gear F in one direction only. This gearing is carried by suitable journal bearings secured to the carriage B.

In order that the rollers C may be rotated,

the drive gear G is arranged to strike a rack H which is preferably so arranged as to cause the rollers C to rotate and advance the object when the carriage is preferably in a position just before passing the knife. Tnstead of the drive gear E a cone gear and several racks might be employed so as to impart a different speed to the rollers G. The rotation of the rollers causes the object to firmly press against a tray J which is arranged to move with respect to the knife so as to regulate the thickness of the slices. The adjustment of this tray is for example effected by a rack K and gear L as shown in Fig. 6: I

The invention operates as follows: The position of the tray J with respect to the knife is regulated by rotating the gear L. The knife is then rotated for example by starting the motor A, although the knife might of course be driven by a rack secured to the reciprocating carriage. The object to be sliced is placed in the chute of the carriage and the carriage reciprocated, preferably by hand. In the course of the reciprocation the drive gear G strikes the rack H, and rotates the bevel gear and the rollers C, thereby pressing the end of the meat against the tray J. As the carriage B is moved past the knife the cutting operation is effected. On the return movement of the carriage, the drive gear again strikes, the rack but rotates idly without actuating the gear train controlling the rotation of the rollers since the pawl drags idly over the ratchet F.

While four shafts and eight rollers are shown obviously any member might be used to advance the object.

It is claimed:

1. A slicing machine combining a knife, a tray to regulate thethickness of the slices and mechanically driven means to press the object against the tray during the cutting operation. 1

2. A slicing machine combining a knife, a

movable tray to regulate the thickness of the .slices, a frame movable relatively to the knife and tray and positively actuated moving members on which the object to be sliced is adapted to rest, the movement of the members causing the object to abut against the movable tray.

3 A slicing machine combining a knife, a

emme horizontally movable frame movable rela tively to the knife and tray, mechanically operated means to press the object to be sliced against the tray during the cutting operation and'means to actuate the knife during'the cutting operation. l. A slicing machine combining a knife, a tray to regulate the thickness of the slices, a frame movable relatively to the lmife and tray, means to press the object to be sliced against the tray during the cutting operation, means operated by the movement of the frame to actuate the last named means and means to actuate the knife during the cuttingoperation.

5. A. slicing machine combining a rotary knife, anadjustable tray having a circular cut away portion, the circular cut away portion being contiguous to a portion of the periphery of the knife, a frame adapted to be moved relatively to both the tray and knife and mechanically operated means to press the object against the tray during the cutting operation.

6'. A slicing machine combining a rotary knife, a tray to regulate the thickness of the slices, a rack, and positively driven means adapted to cooperate with the rack to press the object against the tray during the cutting operation.

7. Object carrying means for slicing machines comprising a reciprocating frame having a V shaped cross section and at least one mechanically driven element lying in a plane substantially parallelto one of the sides of the frame andstanding out therefrom a suflicient distance so that the object to be sliced when placed in the frame rests on said element. a

8. A slicing machine combining a knife, a tray to regulate the thickness of the slices and means actuated by the movement of the tray to press the object to be sliced against the tray during the cutting operation.
